i was wondering if it is harder to pass smog if your engine is street-ported?... or can you even pass at all?...

-thanks

 

generally it does get harder to pass emissions the larger the porting goes. a mild street port shoudl still pass emissions,

but all shops that ofer porting warn that and medium or larger street ports theres no garentee on passing emissions anylonger.

 

I'm only installing a stock jspec engine in my FC. I'll never pass emissions again lol!
